There is evidence that the human species has evolved from the
oceans.Our veins are filled with salt-water.Our lungs appear to
be formed from a system of gill-like slits.

Slowly, over a
long period of time, our mammalian ancestors emerged from the
oceans to populate the land.

Some mammals, such as whales,were forced to return to the ocean,presumably because of their
great sizewhich ultimately became more of a liability on land
than in the buoyancy of the sea.

Many species of fish eventually
return to the streams where they were born.Some fish, such as
salmon, after swimming thousands of miles over a virtual
lifetime, return to the exact spotwhere there eggs were
deposited and hatched.

Humans have remained on land, and haveroamed the oceans only with the assistanceof hydro-navigational
equipment.

In all races and cultures, humans find the needto return to their place of birth, to where they grew up as a
child, where they spent theirformative years.

This
tendency gets stronger with age, andprobably represents the origins
of what iscommonly referred to as nostalgia.

It is quite possible that the
sensations and feelings associated with nostalgia are a by-product, or side-effect of this most basic instinct, an inherent
tendency to return to our beginnings, directly traceable to the
millions of years whichwe spent as creatures of the oceans.
